Howdy folks,
For my elite status miles on AA, 500 or more that are two weeks late in posting and I'm on the phone, so far that has always resulted in immediate posting.
For idine miles, I give it 3 months to post and so far, everything has always posted.
For Avis, I wait 2 months to see them post (miles into AA).
For everything else, I wait a month after I expect them to post and call.
So far I've been lucky, almost all my miles have posted without intervention from me.
Keep the faith,
Pakse
